Purpose: To assess the real-world outcome of best-corrected visual acuity after 2-year intervention for treatment-naive diabetic macular edema since the approval of anti-vascular endothelial growth factor therapy.
Methods: A total of 1,780 treatment-naive eyes with diabetic macular edema for which intervention was initiated between 2015 and 2019, and which were followed for 2 years, were extracted from the longitudinal medical records of 37 retinal disease institutions in Japan. Interventions included anti-VEGF therapy, topical corticosteroid therapy, macular photocoagulation, and vitrectomy. The baseline and final best-corrected visual acuity, and the number and timing of interventions were recorded. Eyes were classified according to the year in which intervention was initiated.
Results: Over a 2-year period, best-corrected visual acuity improved annually, finally reaching seven letters. The proportion of eyes in which good vision was maintained (best-corrected visual acuity >20/40) increased to 73.3% in the latest period. The administration of anti-VEGF therapy remained stable, accounting for approximately 90% of eyes. Notably, the proportion of eyes receiving anti-VEGF drugs as first-line treatment increased dramatically to approximately 80%.
Conclusion: Anti-VEGF therapy has become the first-line treatment since the approval of anti-VEGF drugs for diabetic macular edema. These findings reflect the evolution of diabetic macular edema treatment and highlight the superiority of anti-VEGF therapy and its increased uptake over time.
